I don't know very much about applets, and I'm trying to learn more using a book. I've already done some applets that contain simple animation, but when I tried drawing an image I've got stock on this: access denied( "java.io.FilePermission" "[image]" "read"). Anyone who can help me? import java.awt.Graphics; import java.awt.Image; public class

See if you can get to draw an image available through a publicly accessible URL. –npinti Jul 28 '15 at 12:13 @Andreea if one of the Answers solved your problem, then please select one to close this question :) –Kami Jul 28 '15 at 23:46 1) Why code an applet? If it is due to the teacher specifying it, please refer them to Why CS teachers should stop teaching Java applets. 2) Why use AWT? See this answer for many good reasons to abandon AWT using components in favor of Swing. –Andrew Thompson Jul 29 '15 at 12:02 access denied( "java.io.FilePermission" "[image]" "read").

Applet runs normal and works perfectly while i am running on ide (intelliJ) . But when i deployed project to .jar file and tried http://stackoverflow.com/questions/34830167/signed-java-applet-access-denied-java-io-filepermission-read to run on browser (firefox) i got some error saying that .jar is untrusted. Then i made some researches and signed my applet with jarsigner . I follewed these steps : keytool -genkey -keyalg rsa -alias MyCert keytool -certreq -alias MyCert jarsigner C:\TestApplet.jar MyCert also tried commands at oracle web site .link here After i signed my applet error gone and i could run my applet. But when i try to sign a file i got an error saying that applet dont have permision to access cert store folder.

After many security vulnerabilities were found, applets (even signed applets) are not given permission to the cert store folder. –Elliott Frisch Jan 16 at 18:47 So do i have any thing to do. I can maybe install lower java version ? :( –salih baki sayer Jan 16 at 18:59 Don't

Same war working fine in Testing environment and only facing issue in production. Even i have added necessary grant permission in "catalina.policy" file similar like my testing region. but still i getting the same set of issue. Can someone please help me on this for finding solution.

Unlike such restricted environments as the Java Applet sandbox, a normal Java application VM (which is what Tomcat runs is) has full read-write access to the local filesystem, including local mounts of remote filesystems. So unless there's something that was added to your catalina policy to forbid it, your problem shouldn't be coming from missing/incorrect Catalina policy. Thus, I'd recommend checking to see if the Tomcat user has appropriate read/write privileges without regard to what program is actually running. Incidentally, it's EXTREMELY hazardous for web applications to write into WARs, regardless
